Practice question from Coordination Compounds (Class 12 · CBSE · Science Chemistry), with the correct answer and a step-by-step solution.
medium · MCQ · Q-1C1631
Which of the following coordination entities exhibits optical isomerism?
- A.[Co(NH3)4Cl2]+
- B.[Co(en)3]3+Correct answer
- C.[Pt(NH3)2Cl2]
- D.[Co(NH3)3Cl3]
Solution
[Co(en)3]3+ is of the type [M(AA)3], which lacks a plane and center of symmetry in both cis and trans forms and hence shows optical isomerism (exists in d- and l- forms).
